What You Need to Know About Connecting an Electrical Installation to a Shed, Summer House or Outbuilding

If you have a summerhouse or a shed that you’re finding yourself spending increasing amounts of time in, you may be thinking about getting an electrical installation so that the space has power. If you’re planning to build a structure in your garden to serve as a home office, a workshop, home bar, studio or as an extension of your living area, then you’re absolutely going to want an electrical supply installed!

Having electricity in your outbuildings offers the ultimate convenience and means you can power everything from a computer and a desk lamp to industrial power tools and fridge freezers!

With this in mind, we’ve put together a guide to getting an electrical installation in an outbuilding, outlining the areas you need to consider before, during and after the work is carried out. Read on to learn more!

Durability

The most important thing that you need to consider and the first thing you need to test is the durability of your exterior structure. The structure must be able to withstand rain, heat and wind and show no signs of any leaks, corrosion or damage. If your building displays any of these signs then you must get them repaired before attempting to have any electrical supply installed.

Planning

When you are sure your building is suitable for electrical installation, it’s then time to start planning where you would like to have the sockets and switches placed. Whilst this may seem like a simple task, it’s always best to think about what you’ll be using the structure for.

For example, if you’re going to be using it as an office then ensure the sockets are within easy reach of your desk so that you’ve not got trailing extension leads on the floor.  If you’re going to be using the structure as a workshop or studio, then you’ll need to ensure the electrical installation can cope with the power demands of any equipment you may be using and that switches or power outlets are placed within easy reach for you once the equipment is in place, so you don’t need to stretch behind your kit to turn things on or off. Lastly, remember to consider where your furniture will be placed once the space is completed so that you won’t be hiding power outlets or light switches behind your furnishings.

Underground or Overground?

The electrical supply cable can be run either overground or underground when connected to the household mains. The underground is the most commonly chosen method, as it eliminates any unsightly cables running through your garden, and will be less disturbed by the weather and wildlife. It is worth noting that the garden will need to be dug out to accommodate the cable when laying and maintaining the installation.

Consulting with your electrician before going ahead with the installation will give you a good perspective of what work needs to be done. This could include the trench for the underground supply, whether or not your fuse board has a spare circuit to connect the supply to, or if you need to have a larger board installed to accommodate it, and other important aspects.
